PIII 667, 256 MB PC133 RAM, Windows XP Pro Build 2600, @ home ISP (disabled proxy), installed win2k speedguide tweak and set RWIN on my own (from reading other threads). Just looking for alternative RWIN values to try. Thanks in advance.

TCP properties for IP
Note: Read the FAQ if the above is not your IP address.
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

TCP options string = 020405b40103030301010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 522600
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 65325
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 20904 kbps (2613 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8361.6 kbps (1045.2 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 47 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Got Cablenut? If so, apply the NIC buffer tweaks below in my sig.:)

Only one left for you, it is not a multiple but a good number anyway 524176:)
